Detailed Description

Represents an operation queue that can run CPOperations.

Definition at line 2 of file CPOperationQueue.h.

Method Documentation

addOperation:()

- (void) addOperation: (CPOperation)  anOperation

implementation

Adds the specified operation object to the receiver.

Parameters

anOperation

the operation that should be scheduled for execution

Definition at line 100 of file CPOperationQueue.j.

addOperations:waitUntilFinished:()

- (void) addOperations: (CPArray)  ops waitUntilFinished: (BOOL)  wait

implementation

Adds the specified array of operations to the queue.

Parameters

ops	The array of CPOperation objects that you want to add to the receiver.
wait	If YES, the method only returns once all of the specified operations finish executing. If NO, the operations are added to the queue and control returns immediately to the caller.

Definition at line 115 of file CPOperationQueue.j.

addOperationWithFunction:()

- (void) addOperationWithFunction: (JSObject)  aFunction

implementation

Wraps the given js function in a CPOperation and adds it to the queue

Parameters

aFunction

the JS function to add

Definition at line 134 of file CPOperationQueue.j.

cancelAllOperations()

- (void) cancelAllOperations

implementation

Cancels all queued and executing operations.

Definition at line 157 of file CPOperationQueue.j.

currentQueue()

+ (CPOperationQueue) currentQueue

implementation

Convenience method for one system wide singleton queue. Returns the same queue as mainQueue.

Definition at line 291 of file CPOperationQueue.j.

init()

- (id) init

implementation

Initializes the receiver

Returns

the initialized receiver

Reimplemented from CPObject.

Definition at line 37 of file CPOperationQueue.j.

isSuspended()

- (BOOL) isSuspended

implementation

Returns a Boolean value indicating whether the receiver is scheduling queued operations for execution.

Definition at line 208 of file CPOperationQueue.j.

mainQueue()

+ (CPOperationQueue) mainQueue

implementation

Convenience method for one system wide singleton queue. Returns the same queue as currentQueue.

Definition at line 277 of file CPOperationQueue.j.

maxConcurrentOperationCount()

- (int) maxConcurrentOperationCount

implementation

Returns the maximum number of concurrent operations that the receiver can execute. Always returns 1 because JS doesn't have threads

Definition at line 190 of file CPOperationQueue.j.

name()

- (CPString) name

implementation

Synthesized accessor method.

Provided by category CPOperationQueue(CPSynthesizedAccessors).

Definition at line 303 of file CPOperationQueue.j.

operationCount()

- (int) operationCount

implementation

Definition at line 144 of file CPOperationQueue.j.

operations()

- (CPArray) operations

implementation

Definition at line 139 of file CPOperationQueue.j.

setName:()

- (void) setName: (CPString)  aValue

implementation

Synthesized accessor method.

Provided by category CPOperationQueue(CPSynthesizedAccessors).

Definition at line 311 of file CPOperationQueue.j.

setSuspended:()

- (void) setSuspended: (BOOL)  suspend

implementation

Modifies the execution of pending operations

Parameters

suspend

if YES, queue execution is suspended. If NO, it is resumed

Definition at line 199 of file CPOperationQueue.j.

waitUntilAllOperationsAreFinished()

- (void) waitUntilAllOperationsAreFinished

implementation

Blocks until all of the receiver’s queued and executing operations finish executing.

Definition at line 174 of file CPOperationQueue.j.
